文摘目的探讨原发性IgA肾病(IgA nephropathy,IgAN)患者不同IgM沉积强度与肾小球超微结构病变及临床病理的关系。方法收集155例IgAN患者的临床病理资料。分为IgM阴性(51例)、轻度(89例)和中度及以上沉积(15例)3组。比较3组间肾小球超微特征性结构、临床指标、MEST-C评分差异并分析与IgM沉积强度的影响因素。结果与IgM阴性、IgM轻度沉积组相比,IgM中度及以上沉积组24 h尿蛋白水平、IgG沉积、肾小管萎缩/间质纤维化(T)评分、足突融合(foot process effacement,FPE)程度更高,血白蛋白水平、淋巴细胞计数更低(P<0.05)。logistic结果显示FPE程度、T评分是IgM沉积强度的独立影响因素。结论IgM沉积强度与原发性IgAN患者FPE程度相关。FPE程度可协同临床病理评分更精准评估肾组织损伤及制定治疗方案。
